The `setupShell` function would update the shell stored on the `Step` object, setting it to either a default value from the job, an expression evaluated in the context of the job, a default from the workflow, or finally falling back to bash or powershell defaults. Typically this would be fine -- although it would trigger the data race detector because the `Step` is a shared object between multiple concurrent matrix evaluations for the job.
In the *really quite unlikely* case that the `shell` field on a step or job referenced a matrix variable, this data race would actually trigger the shared step's `Shell` value to end up as "whichever one was evaluated last", causing the wrong shell to be used. The new `matrix-shell` test triggers this behavior, and fails without the associated code fix.
As a fix, the `Shell` field in `Step` is never mutated; instead only the value on non-shared `stepRun` instance is updated from `setupShellCommand`. `Shell` was renamed to `RawShell` as part of verifying all references were updated and it seemed to make sense to keep that name since it is a pre-evaluator value.

This is a followup of https://code.forgejo.org/forgejo/act/pulls/170 so that it is possible to read a workflow without validation. It is not uncommon for Forgejo to read a workflow just to extract a few information from it, knowing it has been validated before. It would be a performance regression if schema validation happened in these cases.
This is a port of https://github.com/nektos/act/pull/2717/files
It is a breaking change in the context of Forgejo and Forgejo runner because it will need to add the new `validate` argument when reading workflows.

Change planner functions to return errors
This enables createStages to return `unable to build dependency graph`
Fix PlanEvent to properly report errors relating to events/workflows
This change does parse the different types of workflow jobs.
It is not much by itself but the start to implement reusable
workflows.
Relates to #826

* fix: rework `setupShellCommand`
* move all logic to separate function so we can test that later
* split `step.Shell` and `step.WorkingDirectory` setup into own funcs
* general cleanup of function
* use `ActPath` to not collide with checked out repository
* use `shellquote.Split()` instead of `strings.Fields()` for better command split
* replace single string concat with `fmt`

fix[workflow]: skipping over the job when `strategy:` is defined but `matrix:` isn't (fixes#625)
fix[workflow]: skip non-existing includes keys and hard fail on non-existing excludes keys
fix[workflow]: simplify Matrix decode (because I "think" I know how `yaml` works) (fixes#760)
